IMPROVEMENT IN BARRELS, CASKS, 86C.

Specification forming part of Letters Patent No. 220,340, dated October 7, 1879; application filed July 28, 1879.

' of the cover and bottom pieces.

My invention relates to the construction of sheet-metal barrels, casks, milk-cans, buckets,

and other like vessels; Vand, it consists in certain details of construction which result in the production of a superior vessel.

To enable others skilled in the art to make my invention, I will describe its mode ot' construction. //In the drawings', a represents the bucket,

/having a bottom, b, alid, c, and a bail or handle, d. In constructing this bucket a, I take a plain sheet ot iron of proper gage, and t'old the upper and lower edges, as at e, Fig. 4, to obtain a double thickness ot' metal in which to form the shoulder for the support ofthe head, and asin the fini hed article the fold c is within the body of t e can, I term the same the int'old.7 'I then`form the sheet into a cylinder, jointed atf, the double thickness of metal being at the end thereof. I then corrugate the cylinder thus formed on a corrugating-machine, the construction of which is well known to those skilled `in the art. The form of the corrugatingdies is such as to make a shoulder, g, of any desired widthat the ends of the cylinder, at the depth of theinfolds e, so as to form a chine, h, ot' any desired size. The bottom b is made in a die under apress, or in other suitable way, and has an inwardly-curved flange, b'. It is set in the lower end of the cylinder, with its. corner b" resting on the shoulder g, and then the chine h is folded inward upon it, as shown at k. This folding operation causes the edges of the infold e to curve inwardly from the shoulder g, as at c', thereby affordingl an additional support for the bottom b.

The upper end of the cylinder is prepared for the lid orcover cby foldingthe double thickness ot' metal at the end of the can-body backward and outward, as at m, making an outer band around the upper end, which, as the lnetal does not stretch, causes the mouth of the vessel to contract or draw slightly in. lIhe lid c is formed by turning its ange c outward, so as to make a reverse flange or an overlap, c, for the edge of the bucket. The lid is then forced into place in the mouth of the can, the folded thickened edge of which has a kind of spring action upon the lid, and compresses its flange slightly after the disk of the lid has passed it. The result of this construction of lid and edge is a joint sufficiently tight for all practical purposes, so that it requires no further operation` than putting on the lid to close the head.

The lid c may be used on vessels having a singlyfolded edge, as in Eig. 5.

In the construction of powder and other cans, casks, and packages where both ends are to be tightly closed, the construction described with reference to the bottom b of the bucket is to be used at both ends. (See Fig. 6.) In case of a powder-keg a suitable bung-hole and bung are to be provided.

In making the fold 7c over the edge ot the head b, I make it rounding, and in that way avoid theshearing action of the edge ot' the head upon the fold, which a more abrupt and closer fold would cause. I am thereby enabled to use a poorer variety of iron without lowering the quality of the can.

It sometimes happens that the heads of powder-kegs are stood upon or dented in by the fall of tools or heavy articles. A straightiianged headl is liable to be forced from its fastenings into the kegs. This danger is entirely obviated by my improved head, in which the curved edge b hooks into the folded edge of the can and sustains the head under downward pressure.

When the vessel is designed to hold butter, lard, or similar substances, I deem it best to solder the joints on the inside of the head smooth, so that the vessel maybe readily cleansed.

The advantages gained by my invention are, its great simplicity of construction, strength, and cheapness.

The ends of kegs, cans, 8vo., are known in the trade as heads, and whenI speak of the bottom b in this description, such description relates with equal pertineucy to the heads of kegs and other like articles.

Having thus described my invention, what I claim, and desire to secure by Letters Patent isl A. sheet-metal can the body of which has a shoulder for the reception of the head, said shoulder having a double thickness of metal, consisting of the folded-in end of the body and 0f the free edge of the infold bent inwardly away from the body, in combination with a head supported by said shoulder and edge of the infold, substantially as specified.

2. A sheet-metal can the body of which has aninfold or double thickness of metal at the end and a rounded inwardly-bent edge to se cure the head, in combination with a head having a Harige bent inwardly at its edge, said inwardly-bent portion of the ange engaging with or hooking intor the rounded inwardlybent. edge of the eau-body, substantially as and for the purpose specified.

3. A can-body having at its end the folded, outwardly-bent, and doubled edge, forming a band thereon, in combination with a cover consisting of a disk having a reverse iiange, the disk of the cover fitting within the doubled edge and supported thereby against internal pressure, the reverse flange of the lid supporting the same against external pressure, substantially as specified.

In testimony whereof I, the said JOHN F. BUDKE, have hereunto set my hand.
